Abstract

L'invention concerne un complexe moléculaire soluble amélioré permettant un apport ciblé d'un polynucléotide à une cellule spécifique. Le complexe moléculaire comprend (a) un polynucléotide, (b) un véhicule constitué d'un agent de liaison du polynucléotide ainsi qu'un agent de liaison spécifique à la cellule qui se lie à une molécule de surface de la cellule et qui se transforme intérieurement en endosome, et (c) un composant bactérien ou un fragment de celui-ci qui effectue la lyse de l'endosome et provoque la libération du polynucléotide dans le cytoplasme de la cellule. Dans un mode préférentiel de réalisation de l'invention, l'agent de liaison du polynucléotide est la polylysine, l'agent de liaison spécifique à la cellule est une asialoglycoprotéine, et le composant bactérien est la listériolysine O. Le complexe moléculaire soluble décrit dans l'invention ainsi que les procédés d'utilisation de l'invention peuvent être utilisés en thérapie pour administrer des gènes et des polynucléotides antisense à des cellules spécifiques in vivo.
